A work vehicle having a fluent material spreader comprising two counter-rotating variable speed impellers adapted to receive and broadcast fluent material. A right-side impeller broadcasts out to a right-side material broadcast width, and left-side impeller broadcasts out to a left-side material broadcast width. Rotational speed of the right-side impeller is commanded to achieve a desired a right-side material broadcast width, and rotational speed of the left-side impeller is commanded to achieve a desired a left-side material broadcast width. Command of the right-side and left-side impellers is achieved either manually by and operator, or automatically by a control system based on sensor input.

The invention claimed is: 1. A work vehicle having a fluent material spreader comprising: a variable speed right-side impeller rotationally attached to the work vehicle, the right-side impeller adapted to receive and broadcast fluent material out to a right-side material broadcast width as a functi
The invention claimed is: 1. A work vehicle having a fluent material spreader comprising: a variable speed right-side impeller rotationally attached to the work vehicle, the right-side impeller adapted to receive and broadcast fluent material out to a right-side material broadcast width as a function of rotational speed; a variable speed left-side impeller rotationally attached to the work vehicle, the left-side impeller counter-rotating to the right-side impeller, the left-side impeller adapted to receive and broadcast fluent material out to a left-side material broadcast width as a function of rotational speed; a right-side command input device adapted to command a desired rotational speed of the right-side impeller, wherein the desired rotational speed of the right-side impeller corresponds to a desired right-side material broadcast width; and a left-side command input device adapted to command a desired rotational speed of the left-side impeller, wherein the desired rotational speed of the left-side impeller corresponds to a desired left-side material broadcast width. 2. The work vehicle described in claim 1 wherein the work vehicle is a combine having a header for cutting crop, and the fluent material is crop material other than grain expelled from the combine. 3. The work vehicle described in claim 2 wherein the header has a cutting width having a right-edge and a left-edge, and wherein the desired right-side material broadcast width extends to the right-edge of the cutting width, and the desired left-side material broadcast width extends to the left-edge of the cutting width. 4. A work vehicle having a fluent material spreader comprising: a variable speed right-side impeller rotationally attached to the work vehicle, the right-side impeller adapted to receive and broadcast fluent material out to a right-side material broadcast width as a function of rotational speed; a variable speed left-side impeller rotationally attached to the work vehicle, the left-side impeller counter-rotating to the right-side impeller, the left-side adapted to receive and broadcast fluent material out to a left-side material broadcast width as a function of rotational speed; a right-side sensor attached to the work vehicle, the right-side sensor adapted to sense a magnitude of fluent material within a right-side target zone; a left-side sensor attached to the work vehicle, the left-side sensor adapted to sense a magnitude of fluent material within a left-side target zone; and a controller in communication with the right-side impeller, the left-side impeller, the right-side sensor, and the left-side sensor, the controller being adapted to increase rotational speed of the right-side impeller when the magnitude of fluent material sensed by the right-side sensor is below a nominal value, and to decrease rotational speed of the right-side impeller when the magnitude of fluent material sensed by the right-side sensor is below a nominal value, the right-side target zone being established such that a desired right-side broadcast width is realized when the magnitude of fluent material sensed by the right-side sensor is at a nominal value, the controller being further adapted to increase rotational speed of the left-side impeller when the magnitude of fluent material sensed by the left-side sensor is below a nominal value, and to decrease rotational speed of the left-side impeller when the magnitude of fluent material sensed by the left-side sensor is below a nominal value, the left-side target zone being established such that a desired left-side broadcast width is realized when the magnitude of fluent material sensed by the left-side sensor is at a nominal value. 5. The work vehicle described in claim 4 wherein the both the right-side sensor and the left-side sensor are acoustical sensors. 6. The work vehicle described in claim 5 wherein the work vehicle is a combine having a header for cutting crop, and the fluent material is crop material other than grain expelled from the combine. 7. The work vehicle described in claim 6 wherein the header has a cutting width having a right-edge and a left-edge, and wherein the desired right-side material broadcast width extends to the right-edge of the cutting width, and the desired left-side material broadcast width extends to the left-edge of the cutting width. 8. The work vehicle described in claim 7 wherein the right-size target zone and the left-side target zone are determined automatically. 9. The work vehicle described in claim 4 wherein the both the right-side sensor and the left-side sensor are electromagnetic sensors. 10. The work vehicle described in claim 9 wherein the work vehicle is a combine, and the fluent material is material other than grain expelled from the combine. 11. The work vehicle described in claim 10 wherein the header has a cutting width having a right-edge and a left-edge, and wherein the desired right-side material broadcast width extends to the right-edge of the cutting width, and the desired left-side material broadcast width extends to the left-edge of the cutting width. 12. The work vehicle described in claim 11 wherein the right-size target zone and the left-side target zone are determined automatically.
